[Solution] PCMTuner Module 31 failed to read Mitsubishi

 Problem:

My PCMtuner work fine on the bench for some ECU's and not for others. For example it read good for module 71, EDC17C46 VW caddy 2013. But when i try to read old ECU model like Mitsubishi module 31, i got a failure message. So when i test two trimnals positive wire and negative black wire by multimeter i see 2v output! not 12v, Now what i do for fixed this issue please?

PCMTuner Failed to Read Mitsubishi ECU

Solution:

For Mitsubishi ECU like E6Txxx you cannot do, you need genuine tractrix openport j2534 with breakout cable, these ecu require 18v programming line (VPP) which pcmtuner not support.

PCMTuner Unlock Audi SIMOS 8.6 in BSL Mode

Image
 SIMOS 8.6 requires unlocking in BSL mode by the appropriate module. BSL is usually boot mode for unlock. Same as PCR2.1 . Example: Audi A7 2012 2.8 fsi simos 8.6 unlock, after read/write simos8.6 with pcmtuner successfully. all resistor 1 kom How to work with blocks that require unlocking (PCR2.1, SIMOS8.6): 1) Check the current lock status in the car, if the check is disabled, you can go to read-write, otherwise follow the instructions 2) Remove the unit from the car, open it, transfer the processor to BSL mode using the connection below (PCR2.1, SIMOS8.6), the work as a whole as in the package 53 (you can use tools like powerbox, and you can do without them) SIMOS8.6 Unlock pcmtuner pinout Red — +12, Black — GND, Yellow — CAN-HIGH, Blue — CAN-LOW 3) Choose "SIMOS8.6 (EEPROM/UNLOCK/BSL) or PCR2.1 (EEPROM/UNLOCK/BSL)" depending of ECU type 4) Click Identification — save ECU data somewhere in a text file. 5) Click Read — save the EEPROM 6) Given that EC...

How to Find Bosch ECU Serial Numbers and Correct Pinouts

Image
 Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify. So all bosch ecus start with serial numbers 028… 026. We just head to bosches page next https://www.bosch-repair-service.com/ Here you search by oe or bosch number, i have random bosch ecu here and it’s 0 281 014 544 and bosch page ends up with a result. We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...

FoxFlash Read and Write Volvo Denso MB279700-9xxx

Image
 Foxflash Volvo Denso MB279700–9xxx works perfectly, just follow the steps of foxflash , reading, unlocking, and writing all done on the bench. PROCEDURE: 1 — Read the Ecu AND unlock the Ecu 2 — Write the ECU READING AND UNLOCKING: Connect the following pinout using the multifunction cable. Start the driver: CAR > VOLVO > TOOLS VOLVO >UNLOCK DENSO MB279700 9641 SH72546R CAN Click on the READ FILE button to read the file. After reading, click on the UNLOCK button to unlock and enable the writing of the control unit. WRITING: Now it will be possible to reconnect the control unit to the car and write the modified file via OBD. Use the following driver: CAR > VOLVO > Model >2.0 DENSO MB279700 9641 SH72546R CAN Alternatively, you can WRITE also the ECU on the table using the pinout on the next page. Note: Compared to the read pinout, the CAN line is moved. FOXFLASH PINOUT FOR WRITING: Just follow the foxflash instructions: read file 15 min, unl...
